[Bug fortran/33884] New: data-initialized unused variables not detected

[tkoenig at gcc dot gnu dot org]

$ cat data.f 
      subroutine foo
      real a
      data a /1.3/
      end
$ gfortran -c -Wall -O3 data.f
$ g77 -c -Wall -O3 data.f
data.f: In subroutine `foo':
In file included from data.f:0:
data.f:2: warning: unused variable 'a'

I'd expect a warning, like g77.
